Unified Gas Kinetic Simulations of Lid-Driven Cavity Flows: Effect of Compressibility and Rarefaction on Vortex Structures

We investigate and characterize the effect of compressibility and rarefaction on vortex structures in the benchmark lid-driven cavity flow.Direct numerical simulations are performed, employing the unified gas kinetic scheme to examine the changes in vortex generation mechanisms and the resulting flow structures at different Mach and Knudsen numbers

Development of new metal matrix composite electrodes for electrical discharge machining through powder metallurgy process

Electrical discharge machining (EDM) is one of the widely used nontraditional machining methods to produce die cavities by the erosive effect of electrical discharges.This method is popular due to the 2003 kia spectra catalytic converter fact that a relatively soft electrically conductive tool electrode can machine hard work piece.Copper electrode

A note on arbitrarily vertex decomposable graphs

A graph (G) of order (n) misbhv tank top is said to be arbitrarily vertex decomposable if for each sequence ((n_{1},ldots,n_k)) of positive integers such that (n_{1}+ldots+n_{k}=n) there exists a partition ((V_{1},ldots,V_{k})) of the vertex set of (G) such that for each (i in {1,ldots,k}), (V_{i}) induces a connected subgraph of (G) on (n_i) verti
